IB Diploma Programme (IBDP)

Reassuringly independent and rigorous, the International Baccalaureate Diploma Programme is a premium entrance qualification to universities around the world, recognised for its academic integrity, range, and the high level of study skills each student must develop to succeed. 

IB Diploma
The IB Diploma Programme continues to set the global standard in secondary education for university-bound students.

The IB Diploma Programme is an academically challenging programme of education, with final examinations, that prepares students aged 16 to 19 for success at university and in life beyond. It addresses students’ intellectual, social, emotional and physical well-being. The programme has gained recognition and respect from the world’s leading universities.

The DP’s broad and balanced curriculum requires students to subject 6 subjects across the final two years of school (3 at higher and 3 at standard level) including multiple languages, experimental science, individuals and societies (history, social sciences and business management), mathematics, and the arts. DP results are based on a combination of end-of-course examinations along with externally-marked or moderated course work.

In the IB’s signature Theory of Knowledge course, students inquire into the nature of knowing and deepen their understanding of knowledge as a human construction. DP students also complete a major independent research project: an Extended Essay in which they conduct in-depth study of a question from one of their DP subjects. subjects they are studying. Self-directed learning through Creativity, Activity and Service (CAS). CAS provides opportunities for self-determination, collaboration, individual growth and accomplishment, and personal enjoyment. It involves students in a range of activities alongside their academic studies that promote originality, healthy lifestyles, and responsible membership in local and global communities through reciprocal service.

DP students take responsibility for their own learning. They develop skills across wide-ranging approaches to learning for critical and creative thinking, collaboration, independent research, self-management and communication.

IB Diploma students gain competitive offers for further study from prestigious universities around the world. Higher education institutions in more than 90 countries admit students based on their IB credentials, and many US public and private colleges and universities offer credit or accelerated courses of study for successful DP examination results. A growing body of evidence documents higher rates of college-going, the wide range of institutions to which IB students gain admission, their preparedness for university-level study, and their successful adjustment to university life.

The DP is ACS’s most demanding and most frequently chosen academic programme. It requires commitment, academic resilience, good time management, and sustained determination to achieve challenging goals.

IB Diploma Programme model


  • Studies in Language and Literature
  • Language Acquisition
  • Individuals and Societies
  • Sciences
  • Mathematics
  • Arts

Students study six courses – usually three at Higher Level (HL) and three at Standard Level (SL). Students must choose one subject from each of groups 1 to 5 – ensuring breadth of experience in languages, social studies, sciences and mathematics.

The sixth subject may be an arts subject chosen from group 6, or the student may choose another subject from groups 1-4.

A bilingual diploma is awarded to candidates who complete and receive a grade 3 or higher in two languages selected from the DP course studies in language and literature, or in studies in language and literature and an individuals and societies or science subject, completed in a different language.

University Recognition

ACS graduates have won places at a wide range of universities and colleges around the world. Every university in the UK now accepts the IB Diploma, and our students regularly enter the top-tier institutions including Oxford, Cambridge, Harvard, and Yale, as well as many within the Ivy League and Russell Group. In the US and Canada, the IBDP and Course Certificates (Higher Level) are increasingly recognised, with many universities conferring credit or advanced placement of up to one year for them.


IB Diploma Grades & Assessment

Each examined subject is graded on a scale of 1 (minimum) to 7 (maximum). The award of the IB Diploma requires a minimum total score of 24, based on the principle that a grade 4 represents a passing level in each of the six subjects. Excellent performance in the six subjects results in a grade 7 for each, or a total score of 42 points. Students can earn an additional 3 points for superior work on the Extended Essay and Theory Of Knowledge. 

Theory of Knowledge (TOK)

This course is focused on developing interdisciplinary and critical-thinking skills. TOK explores the interdisciplinary nature among subject disciplines and encourages critical reflection and analysis.

Extended Essay

Students must select, research, and write an in-depth, independent research work of 4000 words in one of their six subjects areas. The Extended Essay requirement offers IB Diploma candidates the opportunity to become familiar with the independent research and writing skills expected at university.

In addition

Creativity, Action, Service (CASS)

All IB Diploma students get involved in Creativity, Action, Service (CAS) work. CAS is a fundamental part of the Diploma experience (and one that sets it apart), helping students to grasp the importance of extracurricular activities as an integral part of life, and as a healthy counterbalance to the world of pure scholarship and study. These initiatives and activities are a key part of our student’s education, and include:

  • the Nepal school building project
  • support of the local Englefield Green Dementia society
  • a commitment to fundraising for Great Ormond Street Hospital
  • support for the Street Invest Charity
  • Model United Nations
  • Sports
  • And many, many more.
